Environmental Claims: Substantiation

The Competition and Markets Authority (CMA) Green Claims Code provides six principles which must be complied with when making environmental claims.  These principles are in accordance with the requirements of consumer protection law. 

The sixth principle of the CMA’s Green Claims Code states that environmental claims must be substantiated. 

  • Claims must be tested against scientific or other evidence.
  • Claims must be substantiated by robust, credible, relevant and up to date evidence.

Review and assess your environmental claims against the Green Claims Code now!  The CMA will carry out enforcement investigations from January 2022.
